The Western world’s love affair with chocolate is well-documented: few people have been known to have tasted it for the first time without requesting more.
(A) few people have been known to have tasted it
(B) few having been known to taste it
(C) it has been tasted by few people
(D) few people have been known to taste it
(E) few people having tasted it

B,C and E are all out....I am torn between A and D....between the two I will settle for D....OA please?

still not sure though!

Bang on -- OA is D

I was caught between A and D

Gosh, tricky one between A and D.

Anyone know why D is preferred over A? I do understand why we
need present perfect "have been known" but don't really understand why
"to taste it" is preferred over "to have tasted it".

Any English rule that we can imbibe in our heads ?

i ALSO have this confusion.
experts pleas help!

Between A & D
A repeats the present perfect form instead of using the infinitive.

I like to have eat ice creams
I like to eat ice creams.

after "have been known" it shud be followed by infinitive. to taste
Hence D
